Here is my current javascript code
var image = iframe.contentWindow.document.getElementsByClassName('productVisu').getElementsByTagName('img').getAttribute('src');
This works in retrieving the URL attribute of an image. However when I try this jquery version:
var iframe = document.getElementsByTagName('iframe')[0];
var doc = iframe.contentWindow.document;
var image = $('iframe').contents().find('.productVisu').$('img').attr('src');
I get the firefox error that this not a function. How do I resolve this issue and get the jquery version working?
Thanks
Change this:
$('iframe').contents().find('.productVisu').$('img').attr('src');
to:
$('iframe').contents().find('.productVisu img').attr('src');
I'm not sure how your original code works, since getElementsByClassName
and getElementsByTagName
return node lists, not individual nodes.
Try this instead:
var image = iframe.contentDocument.querySelector(".productVisu img").src;
Never use jQuery when you can use Vanilla JS . It's like turning a screw with a sledgehammer.
I don't understand the need for the first two lines of code in your example. You could easily do this:
var image = $('iframe').eq(0).find('.productVisu img').attr('src');
